Organisms carry out a complex set of chemical reactions in order to function.
Prior to the 1850s, it was thought that living things existed and functioned outside the laws of physics and chemistry – that they had a unique “life-force” that made them different to non-living things.
In the 1850s, research by Louis Pasteur provided the first strong evidence that chemistry was an important part of life. He found that a number of natural chemical reactions had to occur during theof grapes into wine. This has become the basis of biochemistry and the study of .
The complex chemistry of cells
Thischemistry forms a complex network of interactions that are responsible for the many different functions a cell carries out.
